I recently purchased an accuset brad nailer (A200BN) and was also given
an old air compressor (SMC brand without the owners manual). My
question is what is the optimum pressure setting for the nailer to work?
The accuset manual doesn't say anything except not to exceed something
like 120 psi. I tried it at 40 psi just to test it out and I found it
would fire a brad perfectly, then the next would only fire half way in
the wood, then the next would leave a dent in the wood with no brad
having fired. I'm hesitant to keep experimenting with this stuff until
I have a better understanding of it. Thanks in advance.
You're using too little pressure. Wood is of varying density and 40
psi may work in one area but not in a more dense area. Also, the fact
that no brad was fired. The way these guns work is that they
essentially use the exhaust air from the firing stroke to return the
piston to the top. If you have insufficient air, the piston doesn't
fully return and the drive pin is lowered somewhat and prevents the
brads from advancing into firing position.
Set the pressure around 80 or so.
